David,

the 9C will do it, partially. Go to 5 point curve (mix 6) set the following --- Master = Elevator, Slave = Flap, Link = On, Trim = Off.
Curve settings:
1=75% (or whatever flap position you want)
2 = 0
3 = 0
4 = 0
5 = -75%
You also need to activate Flaperon.

What does all this mean? When elevator stick reaches point 2 (which is between neutral and full elevator stick movement) spoilers will start to come up, but they don't snap to a certain position. As you move from point 2 to point 1, the spoilers will come up to 75% at a linear relationship. This info contradicts my previous email. I just looked at my 9C, and remembered how it works.

In a nut shell. When you pull back on elevator to 50%, spoilers start coming up. When you pull all the way back on the elevator, the spoilers come up to 75%.

I hope this helps.
